2 Claims.

This invention relates to a feeding apparatus for conveyers and has relation more particularly to an apparatus of this kind especially designed and adapted to feed very fine material, such as cotton linters, ground up rubber or any material in a pulverized or partially pulverized condition.

It is a primary object of the invention to provide means whereby the material is delivered by the feeder to a wire screen conveyer in a manner to prevent the stock or material from sifting through the conveyer.

It is also an object of the invention to provide means to break the fall of material or stock as it travels toward the conveyer so that the said material or stock will be lightly or gently received upon the conveyer.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved feeding apparatus for a conveyer whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure 1 is a fragmentary view partly in section and partly in elevation illustrating a feeding apparatus for conveyers constructed in accordance with an embodiment of my invention, certain of the parts being diagrammatically indicated by broken lines;

Figure 2 is a view partly in elevation and partly in longitudinal section taken through the roll as herein comprised to break the fall of ma- 40 terial or stock as delivered to the conveyer;

Figure 3 is a fragmentary view partly in section and partly in elevation illustrating another embodiment of my invention.

In the embodiment of the invention as illustrated in Figures 1 and 2, H denotes a hopper into which the stock is initially deposited and which stock is carried upwardly by the outer stretch 1 of the endless apron A passing around the suitably positioned guide drums or rollers 2, one of which and preferably the uppermost drum or roller being power driven at a desired speed of rotation depending upon the preferred rate of travel of the apron A. The material carried by the apron A out of the hopper H is dropped down upon a deflecting panel P supported between the side walls 3 and which panel P comprises a flat member or plate held stationary between said side walls and disposed on an inward and downward incline and terminating preferably a distance inwardly of the receiving 5. end of the upper stretch 4 of the dryer conveyer C which travels in a well known manner through a heating chamber B from an enclosing housing.

The lower end of the panel or plate P terminates a distance above the upper stretch 4 of the conveyer C suilicient to permit the placing between said lower edge of the panel P and the upper stretch 4 of the conveyer C of a rotatable drum R. This drum or roll R is of a length substantially equal to the width of the conveyer C and has its extremities defined by the outstanding flanges 5 which provide end walls or heads for the buckets 6 which are afforded between the flanges 7 extending along the drum or roll R from end to end in a direction lengthwise thereof and spaced apart in a direction circumferential of the drum or roll.

The lower edge of the panel P terminates closely adjacent to the line of travel of the outer edges of the flanges 7 or the outer open faces of the buckets 6, and the axis of the drum or roll R is so positioned that the outer edges of the flanges 7 or the outer open faces of the buckets 6 closely approach the upper stretch 4 of the conveyer C as the drum or roll is in operation. It is also preferred that the axis of the drum R be located below the plane of the outer face of the panel or plate P.

As the material or stock travels down the panel P the same will be received within the buckets 6 and the speed of rotation of the drum R is such as to gently or lightly deliver upon the upper stretch 4 of the conveyer C the material or stock within the buckets. This is of particular advantage when the stock or material is in a pulverized or partially pulverized condition, such as fine cotton linters, ground up rubber, etc.

By providing means to effect this light or gentle placement of the stock or material upon the upper stretch 4 of the conveyer, the discharge of the stock or material is prevented from being delivered to the screen conveyer with such force as to cause the material to sift through the conveyer C. The drLun R may be driven in any desired manner but as herein disclosed the same has a driving connection, as at 8, with a motor M. The motor M is also in driven connection with one of the guide drums or rollers 2 and the sprocket and chain assembly speed than the travel of the apron A. This increased peripheral speed of the roller R is of particular importance as it assures carrying away of the material faster than it is delivered by the apron A and thus eliminating the backing up of the stock or material upon the panel P.

In the embodiment of the invention as illustrated in Figure 3, the general construction and assembly is the same as has hereinbefore been set forth in connection with the invention as illustrated in Figure 1 except that the drum R has its periphery free and unobstructed instead of being provided with buckets as in the first embodiment of the device. The drum or roll R substantially closes the space between the lower edge of the panel or plate P and the upper stretch 4 of the conveyer C and said drum R extends a distance beyond or what may be termed above the outer or working face of the panel P so that the material or stock sliding down said panel or plate P will be sufiiciently retarded by the drum R to assure such material or stock being lightly or gently delivered upon the upper stretch 4' of the'conveyer C.

From the foregoing description it is thought to be obvious that a feeding apparatus for a conveyer constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:-

1. In combination with a screen conveyer, a panel for directing stock tothe conveyer, the stock passing by gravity down said panel, the delivery end of the panel being spaced from the conveyer, a rotatable member disposed in the space between the panel and the conveyer, the

periphery of said member being provided therearound with a series of circumferentially spaced buckets, a travelling conveyer for delivering material from the source of supply to the panel, a driving shaft therefor and means driven by the driving shaft for moving the conveyer and for rotating the memberat a peripheral speed faster than the travel of the conveyer.

2. In combination with a screen conveyer, a panel for directing stock to the conveyer, the delivery end of the panel being spaced from the conveyer, a rotatable retarding drum disposed within the space between the panel and the conveyer and upon which the panel discharges, the periphery of said member being unobstructed, an upwardly'and inwardly extending travelling conveyer for delivering material from the source of supply to the panel, and, means for driving the last named conveyer and means for driving the drum from the driving means by the conveyer at a peripheral speed faster than the travel of the conveyer.
